If you were not nervous I would be more concerned. It's perfectly normal to be nervous. It will go away with time but will return when you do certain things, but probably not near as bad.

I have several hundred flights and I still get nervous when I have not flown in a while, I am taking a new plane up for it's first flight, doing a more complicated manuver for the first time and a host of others.

It's all good though as it keeps you sharp.
